This girl is slimmer but I thought it could have been her at an earlier stage of her career. They both have that ethnic look (Judith Barcelona is from Morocco) and they both worked around the same time period. The model was also referred to as Judith in the magazine.

Taking a look at the images in the thread provided by rotobott (thanks, rotobott!), we see her referred to as "Angela" in the photoset published in a magazine. Unfortunately, that doesn't tie her back to any of the names of the ladies in the cast of "Satin Lover", but it may be a clue.
